1 Claimr ,(Cl. 20-69) This invention relates to Weather stripping and it is one object of the invention to provide weather stripping formed of metal and of such formation that it may be easily applied to. a

- window frame and sashes and when in place serve very effectively to prevent air or rain fromv driving inwardly through awindow about the sashes.

Another object of the invention is to so form the metal weather strips that strips mounted at window.

Another object of the invention is to so form the weather strips that they may be manufactured in stock lengths and cut for use according to the height of aqwindow or door to which they are to be applied, strips of the same formation being usable either in connection with slidin sashes'or hinged sashes or doors.

The inventionis illustrated in the accompanying drawing, wherein" Figure 1 is a perspective-view partially construction applied to a window frame and sliding sashes.

in sec-. tion and showing weather strips of the improved i Figure 12 is a perspective view and a modified form of weather strips for use in place ofthose shown in Figure '11. I y t The metal weather stripping constituting the subject-matter of this invention is for use in connection with a window frame I having the usual side portions 2 rising from a lower sill "3 and each carrying the parting strip 4 defining tracks for the upper and lower sashes 5 and 6. The parting strips 4 are formed of upper and lower sections 4 and 4 as shown in Figures 3 and 7, and between abutting ends of these sec-; tions which are recessed, as shown at 1', arefitted felt pads or blocks 8 which are held in the recesses by screws .9 and serveto provide 010860011. tacting engagement with the sashes and prevent rattling of the sashes in the frame. Kerfs it are formed in the cross bars 5 and. (5 of the sashes to receive the parting beads. While it has been stated above that the pads 3 are formed of felt, it is to be understood that rubber or any I other desired, material may be used to prevent rattling'ofthe sashes. 1'

Tight joints must be formed along the por-. tions of the sashes which contact with the parting head or strip 4 and, in order to do so, there have been provided sealing strips II and I2 which "are carried by the window frame and cooperating with companion sealing-strips l3 and M carried by the sashes and disposed within. recesses or kerfs l5 formed along side portions of the sashes; The kerfs I0 constitute, lateral. extensions ,ofthe kerfs 15. The sealing strips H .and I2 are of a duplicate construction and may be cut from the same stock or master strip when weather-stripping a window, it being only necessary to turn a strip II end for end in order Figures 1 and 2. The sealing strips I3 and I4 are also of a duplicate construction and formed from the same stock, it being also only necessary to turn a strip [3 end for end to form a strip M of it. The strips I l and I2 are each formed as shown in Figure 4: or Figure 5, and referring to these figures it will be seen that each strip is formed of metal which is pressed or otherwise shaped to provide an angular attaching portion 16 which extends into the groove in which the parting bead 4 is seated and is provided With a side flange I1 to engage back 'of the parting head. By providing the attaching portionv with the flange H, the sealing strip will be firmly anchored to the frame and prevented from accidentally slipping out of place. The remainder of the strip is bent to provide a channel l8 having a bill-forming flange or lip l9 which may be disposed opposite the frame engaging shoulder 20 of the sealing strip, as shown in Figure and in Figures 1 and 2, or. out of opposed relation to this shoulder, as shown in Figure 4.

The sealing strips l3 and It may be constructed as shown in Figure 9 or as shown in Figure 10. Referring to these figures it will be seen that each sash-carried strip has a channel 2| and an attaching portion 22, the only difference between these embodiments of the sash-carried sealing strip being the fact that the strip of Figure 9 has its bill or lip 23 disposed out of opposed relation to the sash engaging shoulder 24 whereas the strip of Figure has its lip 23 in opposed relation to the sash engaging shoulder. The attaching portion 22 engages in a groove 25 formed in the sash and leading from the kerf l5 and since a tight fit is established the sealing strip will be held firmly engaged with the sash and prevented from slipping out of place. Re ferring to Figures 1 and 2 it will be seen that the companion sealing strips II and I3 and I2 and I4 are so proportioned that when they are applied to the window frame and the sashes, their channeled portions will have interfitting and interlocking engagement with each other, as shown in Figures 1 and 2, and a close fit established which will prevent air from passing between the frame and side edge faces of the sashes.

Instead of providing companion sealing strips carried by the frame and the sashes, the construction illustrated in Figure 8 may be employed. In this embodiment of the invention, the sealing strips, which are indicated by the numeral 26, are quite similar in construction to the strip illustrated in Figure 4 but the folded portion 2! is tightly compressed to form a flange or lip of double thickness which is slidably engaged in a groove 28 formed in the sash. A companion sealing strip carried by the sash is not necessary as the lip or flange 21 fits intoa narrow groove and air can not readily force its way around the sealing strip.

When the sashes are closed, tight joints must be provided between the window frame and the lower edge of the lower sash and the upper edge of the upper sash. Identical sealing means are used at the top and the'bottom of the window and each consists of a strip 29 nailed or otherwise secured to the window frame and bent to provide a flange 30 of double thickness which is received in a groove formed in the companion sash when the sash is closed. By forming a flange of double thickness danger of the flange being bent when a sash is closed will be eliminated and also the flange will be formed with a transversely rounded free edge which will be dull and cannot cut a persons fingers when closing a window.

The space or crack between confronting faces of the meeting cross bars 5 and 6 of the sashes must be sealed to prevent air from passing between them. Therefore, there has been provided metal strips 3! and 32 which are secured in recesses formed in the confronting side faces of the cross bars. The lower edge portion of the strip 3| is bent to form a channel or gutter 33 which engages in a groove or recess 34 formed in the cross bar 6 when the sashes are closed and receives the lower edge portion of the strip 32 which is folded back upon itself, as shown at 35, to provide a reinforced edge portion of double thickness. By folding the strip 32 back upon itself a close fit will be established between the strips when the sashes are closed and undesired bending of the strip 3| will be prevented. The fact that the strips 3! and 32 interfit, as shown in Figure 1, when the sashes are closed prevents air from passing between them.

In Figure 11 there has been illustrated companion strips 36 and 31 for use upon a frame and a swinging door or window sash. The strips are secured against the frame and along the free side edge portion of the door or hinged sash and when the door or sash is closed the channeled portions 38 and. 39 make contact with each other to provide an air tight closure. The strips 31 may also be used for sealing metal sashes when disposed as shown in' Figure 6. If so desired, the strips 4!) and 4| shown in Figure 12 may be used in place of those shown in Figure 11. These strips are secured to the frame and along the hinged door or window sash and when the door or sash is closed, the flange 42 which is folded back upon itself is engaged in the channel 43 of the strip 40. This provides a very tight seal as the flange 42 has a wedging fit within the channel 43. i

It will thus be seen that means has been provided for very effectively sealing a window errtirely about margins of both the upper and lower sashes and also between confronting edge faces of the sashes when they are closed.

Having thus described the invention, what is claimed as new is: v

A window frame, dividing beads extending vertically in said frame at the sides thereof and defining inner and outer tracks, upper and lower sashes slidable in said tracks and having their side edge faces formed with longitudinally extending kerfs having open sides confronting the beads, metal sealing strips extending along opposite sides of said beads and having portions extending laterally from the beads against the frame and bent to provide portions extending inwardly from the frame along the outer side edges of the laterally extending portions into the kerfs against side walls thereof and bent back upon themselves to form lips defining open channels, and companion sealing strips carried by said sashes and having portions extending into the kerfs along the open sides thereof and bent inwardly back upon themselves to form lips interengaged with the channels of the first strips and defining channels receiving the lips of the first strips, th interengaged portions of the companion strips filling the kerfs and providing airtight joints between the frame and the sashes.
